BRICK-DRYING KILN AND CAR TO BE USED THEREIN.

SPECIFICATION formingvpart of Letters Patent No. 374,540, dated December 6, 1887. I

' Application filed March 14, i857. Serial No. 230.872. (No model.)

To all whom it 71mg/ concern:

Beit known that I, J. BITN'ER KEMP, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Kilns for Drying Brick and Gars to be Used Therewith; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in drying kilns or tunnels for brick and other purposes, and to cars specially adapted for use in such kilns.

The object of my invention is to provide a drying-kiln in which the articles are dried by hot air coming up through the sheet-iron door and through lues which are disconnected from the furnace, whereby the articles are removed from direct contact with the tire. Another object of my invention is to construct the cars on which the articles to be dried are placed so that they will be brought down close to the bottom of the kiln and brought at once into Contact with the hot-air currents.

In an application led by me September 14, 1885, Serial No. 177,005, I have shown, described, and claimed the tire-arches extending from the furnaces locatedat one end of the kiln to the other, said lire-arches being separated from the drying-oven by a sheet-iron door, and while I have shown the general construction of the kiln as embraced in the application above referred to, in this application only such portions will be claimed as are necessary to vpoint out the improvements.

Referring to the drawings, Figure 1 is a ver- Fig. 2 is a detached portion in section, showing the hot-air tlues at their point o f entrance into the kiln. Fig. 3 is a longitudinal sectional view of the drying-kiln. Fig. 4 is a side elevation of the car on which the articles to be dried are placed. Fig. 5 is a detached view of the friction-bearings of the axles of the car. Fig. 6 is a top or plan view of the car.

A indicates the side walls of the kiln or arch, the space between said walls being divided into two drying chambers or compartments, B, by a central or partition wall,'C. The ends of the chambers or arches B are provided with suitable doors through which the loaded cars are placed into and removed from the dryingchambers, said cars being adapted to travel on the tracks or ways D, located in the bottom of said chamber.

E E are re or hot-airlines which lead from the furnace, located at the side of the kiln and at the front end of the same, to the chamber F, located at the rear end of the kiln, and through said chamber F communicates with.v the smoke-stack G. AThe fire tlues or arches EE run parallel With the sides of the kiln, and are separated therefrom by means of the metal door H.

I are air-dues located in the outer and partition w-alls of the kiln, said ues being connected to the drying-chambers B at suitable intervals by means of the dues K. The object of these air-dues I is to conduct fresh air from the outside to the interior of the kiln, said air being heated in its passage through the tlues I by the heat transmitted from the tire-dues E through the walls of said lues E.

The construction j ust described is essentially the same as that embraced in the application above referred to.

I will now proceed to describe the devices which I consider as improvements on the former construction.

In order to utilize the heat which would be L in the bottom or a short distance below the bottom of the main tire tlues or arches E', so that the heat therefrom will be utilized to heat the air in its passage therethrough. One end of the pipes L is connected to the air-chamber M, which communicates with the external air. The other end of the pipes L is bent outward and .upward and enters the front end ofthe chambers B, as indicated in Fig. 2.

L are pipes similar to the pipes L, which eX- tend from the air-chamber N and enter the chambers B near the center thereof, as in the case of the pipes L. It will be noticed that the heat which passes through the walls and bottom of the fire tlues or arches E and E', and which would be otherwise wasted, is utilized to heat the air in the pipes L, to effect the drying of the articles in the drying-chambers B, forming an induced current in the direction of the flue or stack A,which carries o the water, smoke, fumes, or gases.`

otherwise wasted, I place the air'pipcs'or fines P indicates the cars, on which the material to be dried is placed. The frame R ofthe car is made of angle-iron, bolted together in any suitable manner, and is supported below the axles of the trueksS, so the articles will be brought near to the sheet-iron iioor ofthe dryingchambers B, which is the hottest portion of the chambers. l 4

T are the axle-boxes, secured to the upper side of the frame R, said boxes being provided with a cavity adapted to receive the frictionballs V and the axles of the truck, thus forming a friction-bearing for the axles which is of a simple, cheap, and durable character yand not liable to be warped or made inoperative by the contractions and expansions incident to the changes of temperature to which they are exposed.

The pallets on which the brick or other articles are placed are arranged on the car-frame, and said frame may be provided with suitable standards and cross-bars which admit of any number of pallets beingr placed thereon in tiers one above the other.

That I claim, and desire to secure by Letters Patent, isa l. In a kiln for drying brick and other material, the firearches located below the door, and a series of air pipes and fines arranged at the sides and in the bottoms of said fire-dues and opening into or communicating with the drying-chambers of the kiln, whereby all the heat is utilized in the drying-chambers.- l

2. In devices for burning or drying brick, a kiln having a sheet-iron floor for protecting the brick from the direct action of the tire, and a car having its supporting-frame suspended below the axles of the truck, whereby the articles on the car to' be dried or burned are brought close to the floor of the kiln,as set forth.

In testimony whereof Iaiix my signature in presence of two witnesses.

J. RITNER KEMP.
